SPECIFICATION forming part of Letters Patent No. 623,925, dated April25, 1899.

Application filed January 3,1899.

Serial No. 700,904. (No model.)

T0 at whom, it may concern;

Be it known that I, THOMAS MOVEIGH, of Danielson, county of Windham,State of Connecticut, have invented an Improvement in Knot-Tying Devicesfor Spoofing-Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters andfigures on the drawings representing like parts.

In United States Patent No. 498,185,

to me May 23, 1893, a knot-tying shown and described particularlyadapted for use in connection with spoofing-machines, hereby the ends ofthreads to be united s evered e'lesetoth'eknotI One o thekiiot tiers wasre *ed-fe-r each spool in said patent, attached by suitable set-screwsto a longitudinally-extended rod back of and above the spools, and whilethe said devices are entirely and satisfactorily operative in practicethe use of such a number on a spooler-frame is too expensive.

My present invention has for its object the production of means wherebya single knottier can be used for tying knots on the ends of yarns fromseveral spools--as, for instance, all of the spools on one side of theframe.

Figure l in front elevation represents a sufficient portion of aspooler-frame to be understood, with my present invention appliedthereto; and Fig. 2 is an enlarged transverse sectional view on the linea: m, Fig. 1, of the knot-tier, the traveler to which it is attached,and the guide-support for the traveler.

The spooler-frame A, spools B, bobbin-holders O, and guides D are andmay be all as common in spoolingmachines, and I have herein illustratedmy invention in connection with such an apparatus.

A non-cylindrical bar a is shown in Fig. 1 as mounted on suitablestandards a above and back of the spools, said bar being shown in Fig. 2as oblong in cross-section and set on edge to form a combined guide andsupport for a traveler adapted to slide thereupon. The travelercomprises a body t, having a hole therethrough corresponding in shape tothe cross-section of and to receive the guide-supgranted device iscross-section might be adopted for the guideport a, the non-cylindricalshape of the latter preventing tipping movement of the traveler withoutinterfering with its lateral sliding movement. Any suitable orconvenient support so long as the non-tipping and free sliding movementof the traveler is attained. The top of the traveler is shouldered at tand provided with an upturned stud t the latter entering the offset boss0 of the knot-tier, which usually rests on the shoulder t and is held inadjusted lateral position relatively to the traveler by a set-screw 20,Fig. 1.

The knot-tying device itself, comprising the body 0, slotted to receivethe shanks of the knot-forming nibs d, the thread-cutter e, pivoted at eat the rear side of the nibs, so as to cut off very close to them theyarns pinched between the nibs, and the combined thread-support andcutter-actuator f is and may be substantially as shown and operating inmy patent referred to.

Obviously the operator can push the traveler along the guide-supportinto position adjacent any spool on the side, according to the yarn tobe knotted, thus enabling a single knot-tying device to serve for theentire side of a spooler-frame. If the frame be a very long one, two ofthe knot-tiers could be mounted on the guide-support instead of one, asherein shown. Each side of the spooler will be similarly equipped.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In an apparatus of the a longitudinally-extendedguide-support, and aknot-tying device free to slide on said support, and means to preventrotation of said device on its support during sliding movement.

2. In an apparatus of the class described, a longitudinally-extendedsupporting-bar,-a traveler non-rotatably mounted thereupon and free toslide along said bar, and a knottying device carried by the traveler.

3. In a spoofing-machine, a longitudinallyextended guide-support locatedabove and back of the spools, a traveler free to slide class described,

just the said device on the traveler,

ter being movable longitudinally of the bar to bring the knot-tyingdevice into position adjacent any desired spool.

In testimony whereof I have signed my name to this specification in thepresence of 15 two subscribing Witnesses.

THOMAS MCVEIGH.
